“…Root architecture traits such as root diameter, length, density, branching, and nodulation are fundamental determinants for promoting robust plant growth under challenging environmental conditions. Improving these root traits has the potential to make a significant contribution to sustainable agricultural development and increased productivity, especially in the face of soil stress factors such as arsenic toxicity ( Fenta et al., 2011 ).…”

“…In present investigation, for the first time, we have employed advanced techniques like synchrotron micro-CT to quantify and analyze various root parameters, including root length, diameter, pore size, lateral root branching, and nodule formation in soybean plants. It is important to note that soybean exhibits a characteristic allorhizic root system, in which a tap root (originating from the hypocotyl) serves as the primary root, from which lateral roots subsequently emerge ( Fenta et al., 2011 ). In the present study, we found significant reduction ( P < 0.01) in the root length and root mass in NP plants exposed to different levels of As toxicity (5, 10, and 50 mg kg −1 ) in comparison to control (0 mg kg− 1 soil) conditions ( Figures 1A, B ).…”

The present study evaluated the repercussions of magnetopriming on the root system architecture of soybean plants subjected to arsenic toxicity using synchrotron radiation source based micro-computed tomography (SR-µCT). This will be used evey where as abbreviation for the technique for three-dimensional imaging. Seeds of soybean were exposed to the static magnetic field (SMF) of strength (200 mT) for 1h prior to sowing. Magnetoprimed and non-primed seeds were grown for 1 month in a soil–sand mixture containing four different levels of sodium arsenate (0, 5, 10, and 50 mg As kg−1 soil). The results showed that arsenic adversely affects the root growth in non-primed plants by reducing their root length, root biomass, root hair, size and number of root nodules, where the damaging effect of As was observed maximum at higher concentrations (10 and 50 mg As kg−1 soil). However, a significant improvement in root morphology was detected in magnetoprimed plants where SMF pretreatment enhanced the root length, root biomass, pore diameter of cortical cells, root hair formation, lateral roots branching, and size of root nodules and girth of primary roots. Qualitative analysis of x-ray micro-CT images showed that arsenic toxicity damaged the epidermal and cortical layers of the root as well as reduced the pore diameter of the cortical cells. However, the diameter of cortical cells pores in magnetoprimed plants was observed higher as compared to plants emerged from non-primed seeds at all level of As toxicity. Thus, the study suggested that magnetopriming has the potential to attenuate the toxic effect of As and could be employed as a pre-sowing treatment to reduce the phytotoxic effects of metal ions in plants by improving root architecture and root tolerance index. This study is the very first exploration of the potential benefits of magnetopriming in mitigating the toxicity of metals (As) in plant roots utilizing the micro-CT technique.

“…This is consistent with soil biochemical indicators suggesting slightly elevated P mineralization in soils under soybean compared to maize cultivation at a high degree of, or complete (i.e., 100%) phytin substitution for MAP, which would be expected to increase with crop P limitation (see Section 4.2). Greater derivation of aboveground biomass P of maize from the soil compared to soybean may be explained by the greater root density and finer roots of maize (Hochholdinger et al., 2004; Fenta et al., 2011).…”

Phosphorus (P) recovery from waste streams can increase food system P use efficiency while simultaneousl mitigating point source P losses. Phytin is a P‐rich waste product generated from maize grain biorefineries, largely located in the US Midwest. However, since the majority of P in phytin is organic, phytin‐P is likely to have limited crop availability in soil following application, as it must first be mineralized to orthophosphate‐P by soil phosphatases. To evaluate the fertilizer potential of phytin recovered from a maize wet milling plant and test hypothesized mechanisms of P mineralization, a five‐step gradient of phytin substitution for monoammonium phosphate (MAP) (0%, 25%, 50%, 75%, and 100% substitution) was evaluated for maize (Zea mays L.) and soybean (Glycine max L.) growth in a P‐deficient Aquic Argiudoll. Irrespective of crop species, aboveground biomass at end of vegetative growth (VT stage) was similar for up to 75% phytin substitution as MAP, but was 21% lower for maize and 49% for soybean when phytin was fully substituted for MAP. Soil microbial biomass carbon (C), nitrogen (N), and P, as well as activities of phosphomonoesterase and phosphodiesterase were invariant across the phytin substitution gradient, suggesting negligible mineralization of phytin P. Full substitution of MAP with phytin lowered soil microbial biomass C:N by 121% for maize and by 153% for soybean, and soil phosphatase activities per unit microbial biomass C were 24% higher under soybean. Our results indicate that phytin can be partially substituted for highly water‐soluble P fertilizers for the two major crop species of the US Midwest in which phytin waste generation is co‐located.
